- Abstract
Operation of wastewater treatment plants (WWTPs) of northeast China become poor generally in winter. In this ar⁃ ticle, five WWTPs in Changchun City, as a study object, were investigated involving the analyses of the microbial composi⁃ tion of activated sludge using high-throughput sequencing technology, and finally the preliminary identification of the core functional microorganisms through the common OTUs and functional characteristics of the dominant genera of activated sludge microorganisms in the five WWTPs. Findings of the study showed that there was no significant difference (P>0.05) in terms of abundance and diversity of activated sludge microorganisms among the above WWTPs; the dominant microorgan⁃ isms of the two ordinal systems were initially identified as Proteobacteria, Bacteroidetes, Firmicutes, Acidobacteria, Actino⁃ bacteria and Verrucomicrobia on the phylum level, and all were associated with biodegradation, while on the genus level were Dechloromonas, Zoogloea, Arcobacter, Ferribacterium, Candidatus_Accumulibacter, Sulfuritalea, and among those related to biodegradable pollutants were Dechloromonas, Arcobacter, Ferribacterium; and those above-mentioned microorganisms had a high probability of being the core activated sludge microorganisms of WWTPs during winter in northeast China. In conclu⁃ sion, results of the study in regard to the identification of core microbial flora of activated sludge in the municipal WWTPs at low temperature and the application of technically regulating the functional bacteria to enhance WWTPs’effluent quality plants during the freeze-up period could be used for reference.
